yany kind or type of electric motors.

Other objects of the invention will appear from the following description at the end of which the invention will be claimed and in connection with which reference will be made to the accompanying drawings formingl part hereof and 1n which Figure. l is a' side view with parts in section. y 5

- Fig. 2 is an end,view with the pulley' and motor omitted, and

Fig. 3 is atop or plan view partly 1n section.

Referring to thedrawings, 1 is a suspension frame shown as comprising a foot 2 for attachment to 'a table as A, a ilat portion 3 for attachment to the base 4 of a motor, and an intermediate curved portion having a web 5. rilhe're is a bracket depending from the frame and the bracket comprises two parts connected by the post 6, One part 7 of the bracket is a slide adjustably connected with vthe frame by bolts and slots 8, and the other art 9 of the bracket is turnably adjustable y the post 6.

The part 9 of the bracket as a portion thereof includes the'braking surface 10, the lears 11, and the parallel pins 12. There is a cross head 13 mounted to move onthe ins 12, and there are springs 14 interposed etween the crosshe/ad and bracket and they are shown as encirclin the pins 12, Fig. 3. The crosshead carries t e revoluble shaft 15 at one end of which there is a driven element 16, and at the other end of which there is a pulle 17, useful for driving a sewing machine. he shaft 15 is shown as mounted in the crosshead by means of annular ball bearings. 18 is a pedal lever having its shaft journaled in the ears 11 and provlded with arms 20 connected with the crosshead 13, or more accurately, with studs 21 at the ends thereof. On the motor shaft 22 there is arranged a driving element 23 spaced from the driven element 16. and the driven element 16 is spaced from the braking surface 10.` When the lever 18 is released the driven element 16 contacts with thebraking surface 10, the springs 14 assisting in moving the` crosshead on the pins l2. When the lever 18 is pulled down its arms 2O move the crosshead on the pins and the driven element 16 engages the driving element 23, thereby rotating the pulley 17.

By means oi' the appropriate bolts and slots 24, motors of diierent styles and sizes may be connected through the base thereof to the bracket, and the shaft 15 can bel properi ly aligned with the motor shaft 22 by the adjustments 6 and 8 already' described. As 'a .whole the device is simple, and the crosshead 4moving on-plns constitutes durable means for shifting the ldriven velement 16.

It will be obvious to those skilled in the art to which the invention relates that modiications may be made in details of construe-g l tion and arrangement and matters of mere.

Iform without departing from the spirit o'f the invention which is not limited to such matters or otherwise than the priorart and the appended claims may require.

1 claim: l

1. rlransmission apparatus comprising in combination spaced'driving and brake elements, a crosshead, parallel guides for the crosshead, a revoluble shaft carried by the I crosshead and provided at one end with a pulley and at the other end with a driven element arranged between the spaced driving and brake elements, and means for moving the crosshead.
